They are activated 3-4 hours before maximum expected >= 110 cm. The sound depends on the forecasted level Sirens warning system Mobile pedestrian raised walkways in case of high tide Joint Research and Collaborations Joint Research and Collaborations Agenzia Regionale Prevenzione ed Ambiente del Veneto: Centro Meteorologico Teolo (ARPAV CMT) Agenzia Regionale Prevenzione ed Ambiente dell'Emilia Romagna: Servizio Meteorologico Regionale (ARPAER SMR) Agenzia Spaziale Italiana (ASI) Agenzia Spaziale Europea (ESA) Centro Euromediterraneo per lo studio dei Cambiamenti Climatici (CMCC) Centro Nazionale Meteorologia e Climatologia Applicata dell'Aeronautica Militare Italiana (CNMCA-AM) Consorzio Venezia Nuova (CVN), Venezia Deutscher Wetterdienst (DWD), Offenbach, Germania Drzavni Hidrometeoroloski Zavod (DHZ) European Organisation for the Exploitation of Meteorological Satellites Ente Nazionale Idrocarburi (ENI) (EUMETSAT) Epson Meteo European Sea level Service (ESEAS) European Centre for Medium-Range Weather Forecasts (ECMWF), Istituto Nazionale di Scienze Marine (ISMAR-CNR) Reading, UK Istituto Nazionale di Scienze dell'Atmosfera e del Clima (ISAC-CNR) European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) Istituto Nazionale di Scienze Polari (ISP-CNR) Istituto di BioEconomia (IBE-CNR) Istituto Nazionale di Oceanografia e Geofisica Sperimentale (OGS) Istituto Superiore per la Protezione e la Ricerca Ambientale (ISPRA) Koninklijk Nederlands Meteorologisch Instituut (KNMI) Magistrato alla Acque, Venezia Osservatorio Meteorologico dell'Arpa Friuli Venezia Giulia Protezione Civile, Venezia Protezione Civile Friuli Venezia Giulia Università degli Studi di Trieste, Dipartimento di Ingegneria Università degli Studi di Trieste, Dipartimento di Scienze Università degli Studi di Padova, Dipartimento di ingegneria idraulica (DICEA) The Venice “acqua granda” Venice 12-13th of November 2019 Exceptional tidal events in autumn 2019 Exceptional tidal events in autumn 2019 Exceptional tidal events in autumn 2019 Exceptional tidal events in autumn 2019 In two month (November and December 2019) it occurred one fifth of the cases registered in almost 150 years Mean sea level rise in Venice Mean sea level rise in Venice Mobile barriers at the lagoon inlets (MOSE) The mobile barriers at the lagoon inlets are being constructed by Ministry of Infrastructure and Transport. Work began in 2003 and it’s expected to be completed by the end of 2021. Venice and its lagoon are on the northern Adriatic sea (immagine da Consorzio Venezia Nuova, www.istitutoveneto.it) Meteorological factors and storm surges at the origin of high water in Venice How EU projects are helping our job I-STORMS and STREAM are two integrated projects. These projects are inspired by a basin scale aproach. To increase the accuracy and reliability of sea storm forecasts is important to use the right scale, that is the adriatic-ionian area. This is only possible through the transnational cooperation. The I-STORMS project I-STORMS is a project co financed Common Understanding by the INTERREG Adrion programme and led by the City of Venice Increased I-STORMS aimed at enhancing knowledge innovative policies and develop joint strategies to safeguard the ADRION Increased skills II-STORMS Network and Permanent area from sea storm emergencies cooperationand Permanent table by: cooperation table -fostering transnational cooperation to by sharing knowledge, data and Increased awareness forecasts among involved countries -improving their capacities in terms of early warning and civil protection procedures Effective early warning systems -increasing accuracy and reliability of sea storm forecasts and thus be able to improve risk preparedness in the Adriatic-Ionian coastal areas The STREAM project Strategic development of flood management STREAM aims to increase the management capacity to promptly react to flood disasters in the Adriatic coastal area by developing: ● Efficient risk monitoring tools and early warning procedures ● flood risk management plans ● flood forecasting system Data sharing, flood cadastre, flood risk maps, exchange of practices and capacity building schemes for the emergency 4th November 1966 Services The project will also contribute to raise awareness about the flood risks in the areas involved and to people will learn how to behave in case of flood hazards.
